part ofcomposed primarily ofimmediate transformation ofganglionA biological tissue mass, most commonly a mass of nerve cell bodies.A ganglion is a cluster of neurons. It is part of a nervous system. It may include glial cells. The neurons are arranged in a specific constellation: neuronal somata are concentrated at the surface, thus forming a cell cortex, and neurites are concentrated in the centre of the ganglion to form the neuropil. A ganglion is a distinct unit but several ganglia may be anterio-posteriorly joined by connectives or transversally by commissuresAAO:0010426AEO:0000135BAMS:GBTO:0000497CALOHA:TS-0397Cranial sensory placodes are focused areas of the head ectoderm of vertebrates that contribute to the development of the cranial sense organs and their associated ganglia. Placodes have long been considered a key character of vertebrates, and their evolution is proposed to have been essential for the evolution of an active predatory lifestyle by early vertebrates.[well established][VHOG]EFO:0000899EHDAA2:0003135EHDAA:2897EHDAA:4662EHDAA:5621EHDAA:918EMAPA:32846EV:0100372FBbt:00005137FMA:5884MA:0002406MAT:0000207MAT:0000343MESH:D005724MIAA:0000207MIAA:0000343NCIT:C12719Portion of tissue that contains cell bodies of neurons and is located outside the central nervous system.[AAO]Structures containing a collection of nerve cell bodies.
